Tainted Observer Rulings
5 most recent
- Feb 4, 2023 A player with ten or more poison counters loses the game. This is a state-based action and doesn't use the stack. In other words, it happens immediately and players can't respond to it, just like a player losing the game due to having 0 or less life.
- Feb 4, 2023 An ability that triggers "Whenever you proliferate" triggers even if you chose no permanents or players while doing so.
- Feb 4, 2023 Any other effects of that damage, such as life gain from lifelink, still apply.
- Feb 4, 2023 Conversely, replacement effects that apply to the number of counters put on a player can modify the counters placed this way. For example, Vorinclex, Monstrous Raider's last two abilities can apply to counters placed this way.
- Feb 4, 2023 Damage dealt by a creature with toxic grants the same number of counters regardless of how much damage is dealt. Notably, if a replacement effect modifies the damage in some way (such as that of Gratuitous Violence), the number of counters given remains unchanged.
